JanusGraph — CWE-407 Scan Result: CLEAN (new scan)

Scanned 2026-03-29. No new O(N²) list membership defects found beyond previously known.

Note: janusgraph-0001 (MultiCondition ArrayList.contains) was previously identified.

Verified new scan:

  • QueryProcessor.allNew: uses HashSet<R> when dedup needed — O(1)
  • Text.tokens: uses HashSet<String> — O(1)
  • IndexSelectionUtil.givenKeys: depends on caller type; not in hot loop
